Anomalous temperature-dependent heat transport in one-dimensional momentum-conserving systems with soft-type interparticle interaction
Daxing Xiong
We here numerically investigate the heat transport behavior in a one-dimensional lattice with a soft-type (ST) anharmonic interparticle interaction. It is found that with the incre…
Fast preparation of W states with superconducting quantum interference devices by using dressed states
Yi-Hao Kang, Ye-Hong Chen, Zhi-Cheng Shi +2
In this paper, we propose a protocol to prepare W states with superconducting quantum interference devices (SQUID) by using dressed states. Through choosing a set of dressed states…
Optical Schrödinger Cat States in One Mode and two Coupled-Modes Subject to Environments
X. L. Zhao, Z. C. Shi, M. Qin +1
Taking the decoherence into account, we investigate nonclassical features of the optical Schrödinger cat states in one mode and two coupled-modes systems with two-photon driving. I…
Magnetism induced by nonlocal spin-entangled electrons in a superconducting spin-valve
Hao Meng, Jiansheng Wu, Xiuqiang Wu +3
In the traditional view, the magnetic moment appearing in the superconducting region is induced by equal-spin triplet superconducting correlations in superconductor () ferromagn…
Quantum simulation of gravitational-like waves in minisuperspace with an artificial qubit
Ze-Lin Zhang, Ming-Feng Chen, Huai-Zhi Wu +1
On the background of the Born-Oppenheimer (adiabatic) approximation, we investigate the geometrical and topological structure in the theory of quantum gravity by using the path int…
Boundness and Linearisation of a class of differential equations with piecewise constant argument
Changwu Zou, Yong-Hui Xia, Manuel Pinto +2
The differential equations with piecewise constant argument (DEPCAs, for short) is a class of hybrid dynamical systems (combining continuous and discrete). In this paper, under the…
